Solution

The correct option is D ANF
An increase in blood volume and blood flow to the atria of the heart can cause the release of peptide hormone called atrial natriuretic factor (ANF). The primary function of ANF is to reduce blood pressure and in turn maintain GFR within normal range.

Antidiuretic hormone, ADH (vasopressin) is released by the posterior pituitary lobe when the blood has high osmolarity (number of solute particles per litre of solution).

When the blood volume and blood pressure decrease, juxtaglomerular cells in the kidneys secrete the enzyme renin. Renin catalyzes the conversion of angiotensinogen to angiotensin II. Angiotensin II stimulates the adrenal cortex to release aldosterone.
